From: Laurent Vivier <[email protected]> The passt networking backend uses functions from the GIO library, such as g_subprocess_launcher_new(), to manage its daemon process. So, building with passt enabled requires GIO to be available.
If we enable passt and disable gio the build fails during linkage with undefined reference errors: /usr/bin/ld: libsystem.a.p/net_passt.c.o: in function `net_passt_start_daemon': net/passt.c:250: undefined reference to `g_subprocess_launcher_new' /usr/bin/ld: net/passt.c:251: undefined reference to `g_subprocess_launcher_take_fd' /usr/bin/ld: net/passt.c:253: undefined reference to `g_subprocess_launcher_spawnv' /usr/bin/ld: net/passt.c:256: undefined reference to `g_object_unref' /usr/bin/ld: net/passt.c:263: undefined reference to `g_subprocess_wait' /usr/bin/ld: net/passt.c:268: undefined reference to `g_subprocess_get_if_exited' /usr/bin/ld: libsystem.a.p/net_passt.c.o: in function `glib_autoptr_clear_GSubprocess': /usr/include/glib-2.0/gio/gio-autocleanups.h:132: undefined reference to `g_object_unref' /usr/bin/ld: libsystem.a.p/net_passt.c.o: in function `net_passt_start_daemon': net/passt.c:269: undefined reference to `g_subprocess_get_exit_status' Fix this by adding an explicit weson dependency on GIO for the passt option. The existing dependency on linux is kept because passt is only available on this OS.
